Using ColdFusion Data Types

The variables you have used thus far are simple variables, are defined, and contain a value. ColdFusion supports three advanced data types that I'll briefly introduce now.

NOTE

This is just an introduction to lists, arrays, and structures. All three are used repeatedly throughout the rest of this book, so don't worry if you do not fully understand them by the time you are done reading this chapter. Right now, the intent is to ensure that you know these exist and what they are. You'll have lots of opportunities to use them soon enough.
